The personal computer industry backed a promising candidate in the ultrabook concept, convincing even a skeptic like myself that a new class of superslim, superlight laptops was the key to exciting consumers. Ultrabooks were well on their way to becoming the PC form factor of the future.

And now, it’s already over. In record time — something less than six months — the ultrabook term has become so overused and amorphous that it’s well on its way to being useless.

Maybe the PC industry should focus less on marketing buzzwords and labels, and more on just making good products people want to buy and use.
